The current study examined students' study behaviours using a diary methodology. Given the limitations of previous investigations, participants were asked to complete daily study diaries for 10 days prior to a course test to assess students' actual study behaviours. Results showed that students engaged in a diverse set of behaviours with only some of them (i.e., active strategies) predicting academic outcomes including test performance, course grade, and overall grade point average. Implications, as well as the need for further research, are discussed. (Contains 1 table and 4 notes.)
